Applicationled May 12, 1922. Serial No; 560,414.

Be it known Athat I, ARNOLD the following a. speciproved arrangement of internal springs that yield to .either forwarder rearward move-Y ment of the vehicle, and thus ei'ectually absorb shocks from Aeither direction.

Another object of the invention is to providea device of this character including a systenrof internal springs andenclosed in an oil tight chamber ywithin the wheeland in which thefsprings and other partsare constantly immersed. With these and other objects in View the Ainvention, consists in certain novelcfeatures of construction as hereinafter -shownandj f described-and then specifically pointed outI in the claims, andin the drawings illustra.- f

Figure 1 is a side Fig. 2 is a sect-ion onthe line 2-2 of 3 is a side elevation from'the outside. l

- Figs. tand '5 are 'enlarged detached perspective views of a ypair offthestop plates. A The improved wheel comprises ya ri-1n' `4member 10 of anysuita'ble materia-l. and

, Located centrally of the rim 10 is a relatively large fiat hub 12 apertured to receive the journal`13 of an axle, aportion of which is shown at 14. y

y Attached to the side facesA 'of the hub are plates .15 and 16, the'plates and the hub connected Y ,preferablyF byr rigidly Extending from the rim of the plate 15 y are projections 18, andv extending from` the rim of the plate 16 are similar projections 19, the projections of the two plates being, thus arranged in pairs.` Connected through shown.V

sockets or recesses 30, eachrecess havingfa" counter .recess 31 in its vouterfwall.

. Fitting in eachalternate recessis a,y stop plate 32, .and likewise, fitting in .eachy ofthe each pair of the lugs. at one ,vof-,the outer -corners is a pintle'member` 20` and swinging `upon each pintleme'mbergis afbearing arm 21.

other alternate recesses is astoporfpulling plate 33.

`Eachof .the stop plates 32 isfprovidedin Y with a stud 34carrying` an anti-fricti0nroll-` ler r35 against each of which oneo'f thearms .21' bears, as shown. 4-

The springs 36are supported at theirends against the hub 12 and the stopk 32 is provided -in sockets 37 and: 38 bearing respeotive'lyv,

of the stop? members 33 lis provided with` a like recess 42' in the outer end .',asshown 'inFigs 4f and 54, the .recesses to engagefzthe stockfp'ortions `of capzscrews 4,3, the heads f 44 of which bear at one Iside over. the -adja'-""1" cent'portion-, of the stop `members-and .areff received in the sockets or recesses 31 x in I the body ofthe rim'. The cap .screws are tapped into the body oftherim 10, and thus serve to` iirmly hold the members 32and `coupled tothe rim. y l Any required number of the stop members 32 and 33 may beemployed, but siXfof veachv are shown for vthefpurpose vofillustration.

`Supported between` eaclf` of the bearing- *Y i' armsl 21 and the hub 12.a're springs' 36, fthe .springs engaging in cupdevices `37;.and38 on the huband the arms .topreventdisplace'vl ment vof the spring when understrainr.y Any p'loyed, b-uttwo are `shown foreach `bearing arms, for' illustration.
